Memory

There are two different memory boards available for the HP NetServer LX Pro and LXe Pro. The memory
board that comes standard in the LX-Series NetServers uses SIMMs, and is identified by its 16 memory
module sockets. The DIMM memory board is an optional accessory, using DIMMs instead of SIMMs, and is
identified by its 32 memory module sockets. The SIMM-type memory board may be configured in one of
two ways, depending on whether the board is in a Model A LX Pro or LXe Pro NetServer, or in a Model B
LX Pro or LXe Pro NetServer.

Model A SIMMs

A memory board has 16 SIMM sockets, each of which may contain a 16 MB, 32 MB, 64 MB, or 128 MB
SIMM. You can install any of these size SIMMs; however, all eight SIMMs within a bank must be the same
size. For model A SIMMs, you can mix either 16 MB and 32 MB or 64 MB and 128 MB SIMMs in Bank 2.
Follow these rules when installing memory:
Only one size and speed SIMM may be installed in each bank.
SIMMs must be installed in sets of four.
If installing only four SIMMs, install them in bank 1.
